The
areas noted in the forecast have the necessary atmospheric conditions
to produce tropospheric bending of VHF, UHF and/or microwave radio
waves. Tropospheric bending extends the range of radio & TV stations well beyond
their normal limit and thus increases interference amongst stations as
well.

If new clickable map format won't work :
1. Do you have Java enabled ?
2. Is your browser up-to-date ?
3. If it still won't work, you can still get the old style webpage by replacing .html by _old.html
